What type of freon does a 1988 Acura Legend use?

retrofit to 134a everyone should have a shop manual for their vehicle, and the library should have a professional shop manual(wiring diagrams and more detailed info) available in the reference section for FREE....make copies of the right sections, and fix it like a PRO!! good luck Dave :) R12, unless someone has converted it to R134A. If a convert was done by a reputable person, then the connection fittings will be the newer quick dis-connect type. The original fittings are the threaded SAE fittings.
